The problem with any recommendation is generally people are going to recommend what they use... but they have no idea what you gear sounds like, or even more important, what you like.
If Rives did your room, I guess you want to buy the best cable you can afford. Everything from mapleshade is junk, so you can cross them off the list. There are lots of cheap cables that people will tout as giant-killers, but they end up only killing your desire to ever use your system again.
My suggestion (which is just as useless as all the others, since I have never heard your system) would be to try Purist Venustus. I have heard the Cary gear and found it to be soft and pudgy around the midrange, and generally lacking in detail. I think the Purist will prevent anymore loss in these areas. They tend to work well where the Cary does not, so it might be a good balance.
There are people from whom you can borrow/audition cables, which is the easiest way to know how it will sound in your room.
